Asked if there were heightened threats to mass transist sytems since the killing of bin Laden, Pistole said:"There are no specific threats to mass or rail transit right now, in the U.S.," said Pistole.

If they wish to have computers avaiable for use in communicating with friends and family from overseas locations then they need to establish sytems outside the DoD main frame and I am sure safeguards can be put in place to ensure security concerns.

I should add that signals from sensory sytems can also result in cognitive but not motor behaviors, and that only a few plants make use of rapid movements in response to environmental stimuli, but that plants do have sensory mechanisms and “behaviors”.
